the destructive effects of improper use of orthodontic elastic bands are well documented in the dental literature. numerous cases of iatrogenic periodontal destruction have been reported since 1870. despite these well-documented hazards, such incidents still occur. this case report describes a patient who was refered to a dentist by his orthodontist for closing the residual midline diastema by ...

Animals store elastic energy in leg and foot tendons during locomotion. In the turkey, much of the locomotive force generated by the gastrocnemius muscle is stored as elastic energy during tendon deformation. Little energy storage occurs within the muscle. During growth of some avians, including the turkey, leg tendons mineralize in the portions distal to the attached muscle and show increased ...

Fibrous bands have been described in the elastic (conducting) pulmonary arteries in 38 cases at necropsy, which represents a necropsy incidence of 14.4%. The fibrous bands are considered to represent one of the end results of episodes of pulmonary embolism. The formation of the bands is described and their significance is discussed in relation to their haemodynamic effects. Most of these bands ...

The paper presents a new version of the existing elastic band algorithm used for path finding, with application in field collaborative robotics and point-to-point movements. places control points on dynamically modifies position these reaction to any obstacles located or moving workspace. are updated robot space (TCP space), represented by set grid-aligned voxels acquired camera system. Repulsi...

Hereditary sclerosing poikiloderma (HSP) is a very rare disease. The clinical features are principally widespread poikiloderma and linear hyperkeratotic and sclerotic bands. We report an 18-yr-old male who presented reticular hyperpigmented lesions on the trunk and extremities since 2-yr-old. Also, linear sclerosing bands appeared on both antecubital and popliteal fossae after yr. Histopatholog...

The purpose of this paper is to describe a traumatic retinal detachment occurring as a result of CrossFit training using an elastic exercise band. The patient sustained an ocular injury from an elastic band during CrossFit training, resulting in a giant retinal dialysis and retinal detachment, which were successfully repaired. Trainers and athletes need to be aware of the potential for ocular i...

Normal tendons, normal palmar aponeuroses and specimens from patients with Dupuytren's disease, namely apparently normal palmar aponeuroses and contracture bands were subjected to elastase and chondroitinase ABC digestion. Maximum Young's modulus, normalized hysteresis loop and residual elongation were determined before and after enzyme treatment. In normal tendons, normal and apparently normal...

time axis could be detected. Hence, one concludes that if the deformation introduced changes in the elastic constants C33 or C44 these changes must be less than one or two percent for strains up to 10—' radian. Such a result is to be expected since the appearance of slip bands on the surface indicates that the deformation was confined to numerous very narrow bands. Within these bands one might ...
